The work permit is denied because once you are 65 years of age, you can not be enrolled in the school health insurance.  And with no health insurance, no work.

I do know of a way around it, but two things will need to happen :

1.- The school will have to need or want you real bad, and be willing to do a bit more work in securing the work permit with the right "guangxi".

2.- You will have to get yourself some private health insurance with an overseas insurance agency that will pay claims in China.  It will be expensive, and you will have to pay for it.

I do know an 83 years old Ex-Pat teaching at a local university a class on movies and TV productions, and this is how he got his work permit.

Hi Ron, sorry buddy, no can do. There has been some cases in the past where Expats were allowed to work until about 68 if they were in administration or boss positions but unfortunately these days we are seeing the Chinese government up hold their local laws. We lost two really experienced legal professionals this year. For two years, it was never a problem but this year has been somewhat different story
